POINT
"
Pr.112
Load inertia ratio" to "
Pr.117
Speed integral compensation" are
transferred to the servo amplifier when the PLC CPU is powered ON or reset or the
PLC READY signal [Y1D] turns ON. When auto tuning is executed and operation is
performed, however, they are changed to the optimum values in the servo amplifier.
At this time, the auto tuning results are not reflected on the AD75.
Hence, if "
Pr.108
Auto tuning" is changed to "2: Invalid" and the PLC CPU is
powered ON or reset or the PLC READY signal [Y1D] is turned ON, the settings
return to the status before auto tuning, and the motor may vibrate.
When it is desired to save the optimum values obtained by auto tuning, set the data
read from the buffer memory addresses 858 to 863 (Axis 1), 958 to 963 (Axis 2),
1058 to 1063 (Axis 3) to
Pr.112
to
Pr.117
, and perform write to flash ROM.
